Subject: [PATCH] Goodness, that was brutal.

The `!-` name doesn't work as a title for the conversion from ReST to
Markdown.  Maybe that's a bug in Pandoc, but more likely it's a legit
syntax gotcha in Mearkdown itself.

    !-
    ^^^^

In ReST turns into:

    !-\^\^\^\^

In the Markdown.  :(

It should be:

    # !-

Instead.

 <p>&gt; The primrec combinator expects two quoted programs in addition to a data parameter. For an integer data parameter it works like this: If the data parameter is zero, then the first quotation has to produce the value to be returned. If the data parameter is positive then the second has to combine the data parameter with the result of applying the function to its predecessor.:</p>
